Biology - Biology Lab Report, Reports

Lab Report OSMOSIS THROUGH A DIALYSIS MEMBRANE: A SCIENTIFIC EXPERIMENT REPORT GUIDELINES You can work with other groups to discuss how your report will be structured and what you will be including in it, but each group must work on its own report. You can write the same concepts, but using your own words. If two reports say exactly the same, the grade will be divided by two. FORMAT Report must be typed, double spaced, font size 12, arial. Your name goes in the upper right corner of the page. TITLE It should have an informative title. Title should give an idea about the content of the report (do not title it ‘osmosis’ or ‘bio 23 lab report’, it is too broad for guessing the content of the report).   SECTIONS The report should have the following sections: Introduction, Materials and Methods, Results, Conclusion, and References cited. Materials and Methods and Results sections are due on _______ and the full report is due ______.   INTRODUCTION You can think in the intro as the background you provide to someone who does not know anything about the subject. The intro should give the reader basic information so he or she can understand the results and the discussion. You may want to include at least this basic information in the introduction: 1. what osmosis is and why it is an important process for the proper functioning of cells, 2. What isotonic, hypertonic, and hypotonic mean, 3.  what a dialysis bag is, and why you use it in this experiment. You should clearly state your hypothesis(es) and your prediction(s) in the intro. See BIO23 study guide (page 102)   MATERIALS AND METHODS You may want to describe each step you did in the experiment but not the results. The idea of the material and methods section is to provide a ‘recipe’ for the reader in case he or she wants to repeat the experiment. Do not write a list (do not copy from the manual something like: 1-…, 2-…, etc). Describe with your own words what materials you used and what you did. The answer to these questions should be included in this section: 1. Why you used a dialysis tube, 2. why you weighted the bags, 3. why you used the solutes you use You may want to describe briefly (in a paragraph or two) what you found in the experiment. Moreover, you should summarize your results using tables and graphs. Each table/graph should be accompanied with a title (so the reader knows what it is about). Graphs should have a title, axes labeled and the units.   CONCLUSION In this section you go back to your hypotheses and predictions and compare them with your results. You have to “discuss” the results: Do your results support or reject your hypothesis? Did you see what you predicted? Why (explain)? Why not (speculate)? Elaborate a little bit on that. You may want to (briefly) propose another experiment that may give more insight into the subject, or propose some improvement in the experimental design that may improve this one.   REFERENCES Any idea or definition that is not yours (this is, something you copied), you should indicate the name of source. GENERAL RUBRIC TO GRADE LAB REPORT Your lab report will be evaluated based on the rubric found below. Use it to as another guideline on what to include in the report.   Criteria (10% each) Proficient (10%) Competent (7%) Novice (6%) Introduction: Concept Demonstrates a clear understanding of the concept Demonstrates an understanding of the concept Demonstrates poor understanding of the concept. Introduction: Context Demonstrates a clear understanding of why this question is important in the field of biology.  Demonstrates an understanding of why the questions is important in the field of biology Demonstrates poor understanding of why the question is important in the field of biology Introduction Content Content knowledge is accurate, and relevant; provides appropriate background for the reader by defining all key terms Content knowledge is mostly accurate, relevant; provides appropriate background by defining most key terms Content knowledge has many inaccuracies and or is out of context; does not provide sufficient background and/or does not define key terms Hypothesis Statement Both hypotheses are clearly stated Only one hypothesis is clearly stated Both hypotheses are not clearly stated Methods Appropriate control is present; Explanation of experimental setup is clear and complete Control is not explained fully; Explanation of experimental setup is unclear Control is missing; Explanation of experimental set up is unclear and/or incomplete Data Collection Data collection is appropriately paced, is accurate, and follows proper laboratory technique.  Data collection is appropriately paced, is accurate, and follows proper laboratory technique most of the time. Data collection is not adequately paced, is inaccurate, and does not follow proper laboratory technique.  Data Presentation Data are summarized in a logical format. Graph axes are appropriately labeled including units, and correctly scaled. Data are summarized in a somewhat logical format. Graph axes are labeled but is missing units or is inappropriately scaled. Data presentation has many logical errors and graphs contain many errors and omissions.  Results: Data Interpretation Demonstrates clear conceptual understanding; Correctly applies the concept to the experimental results. Demonstrates conceptual understanding Applies the concept to the experimental results with only minor errors or omissions. Demonstrates poor understanding; Fails to apply concept to the experimental results. Conclusion Conclusion is clear and free of logical errors.  Conclusion is mostly clear and has only minor logical errors.  Conclusion is unclear and major logical errors. Conclusion: Logical Reasoning A logical chain of reasoning from hypothesis to data interpretation to conclusions is clearly explained A logical chain of reasoning from hypothesis to data interpretation to conclusions is apparent. A logical chain of reasoning is not apparent.
